Features

■ Wide gain bandwidth: 1.3 MHz ■ Input common-mode voltage range includes ground ■ Large voltage gain: 100 dB ■ Very low supply current per amplifier: 375 µA ■ Low input bias current: 20 nA ■ Low input offset voltage: 5 mV max. (For more accurate applications, use the equivalent parts LM124A-LM224A-LM324A which feature 3 mV max.) ■ Low input offset current: 2 nA ■ Wide power supply range: – Single supply: +3 V to +30 V – Dual supplies: ±1.5 V to ±15 V

Description

These circuits consist of four independent, high gain, internally frequency compensated operational amplifiers. They operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.

2 Absolute maximum ratings

Table 1. Absolute maximum ratings

  1. Either or both input voltages must not exceed the magnitude of V CC
  2. Short-circuits from the output to V CC can cause excessive heating if VCC > 15V. The maximum output

from simultaneous short-circuits on all amplifiers.

  1. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the

for a large overdrive) for the time during which an input is driven negative. This is not destructive and normal output is restored for input voltages above -0.3 V.

  1. Short-circuits can caus e excessive heating. Destructive dissipation can result from simultaneous short-
  2. Human body model, 100 pF discharged through a 1.5 k Ω resistor into pin of device.
  3. Machine model ESD, a 200 pF cap is charged to the s pecified voltage, then discharged directly into the IC

with no external series resistor (internal resistor < 5 Ω), into pin-to-pin of device.

  1. The direction of the input current is out of the IC. This current is essentially constant, independent of the

state of the output so there is no change in the load on the input lines.

  1. The input common-mode voltage of either input si gnal voltage should not be allowed to go negative by

can go to +32 V without damage.

Macromodels LM124-LM224-LM324

5 Macromodels

Note: Please consider the following before using this macromodel: All models are a trade-off between accuracy and complexity (i.e. simulation time). Macromodels are not a substitute to breadboarding; rather, they confirm the validity of a design approach and help to select surrounding component values. A macromodel emulates the nominal performance of a typical device within specified operating conditions (temperature, supply voltage, etc.). Thus the macromodel is often not as exhaustive as the datasheet, its purpose is to illustrate the main parameters of the product. Data derived from macromodels that is used outside of the specified conditions (V cc, temperature, etc.) or even worse, outside of the device operating conditions (Vcc, Vicm, etc.) is not reliable in any way.
